What specs do you have now? What kind of games?
Its Zen 3I was more leaning toward a completely new build but could only afford to do one thing first new cpu/mobo/ram or a new gpu although i think i read somewhere that Zen4, as well as big navi, is going to be revealed soon.
Its Zen 3
Grab a new gpu first yeah we know it will be bottlenecked some what by your cpu but it will probably be the biggest impact on performance.
The only nagging doubt I have is would a 3080
Work In a n older motherboard as the last bios update for your board was 4 years ago.
This can easily be found out when others do the same.
Iv not noticed any bottlenecking as yet, what do i have to look out for when that happens? is it 100% CPU usage or the other way around?
